Not a dumb question at all. Need? I don't think I could make that argument. If you're talking about drop in LED replacements in a reflector housing, that's generally not a good idea. I don't have personal experience with them related to the RS. They tend to put a lot of uncontrolled light out in all directions.Ok, stupid question: is there a functional need for LED bulbs?
The Morimoto retrofits that we're talking about on this thread have a projector lens to control light placement. They have a nice low cutoff and put out a wide spread of light. They allow better visibility around tight corners. Where I notice them the most is pulling into a dark driveway at relatively low speed on a street without any ambient light.
